Jet ski propeller By Andreas Gkertsos on 28 Nov 20:03

Hi Andreas,
you are keen on marine things which is fun.
The real challenge with modeling propellers is developing the aerofiol cross sections which are wrapped about the rotational axis. Without this they will cavitate and be of little practical use.
Ideally both front and rear sides of the propeller will be one foil surface.
Blade thickness will also vary from the hub root out the edge rather than be uniform. Challenging modelling indeed. Keep it up. Cheers Paul

Thank you for your Information Paul!! I'll try to do my best in my next propeller model:) I think that this one must be designed good cause i have one of these in my dad's workshop and i modeled with the real one in hand.. I'll take your advise though. Cheers Andreas.
